Session-Aware Whiteboard Memory Erasure for Secure Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sensitive information shared in group settings is often inadvertently left exposed, posing a security risk due to the lack of effective measures to secure displayed information across multiple devices.
Innovation Solution
A method and system that establish a session between a whiteboard and a laptop, maintaining session awareness through periodic 'heartbeat' signals, and automatically deleting input information from the whiteboard's memory when the session ends, ensuring secure storage and erasure of sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information is shared or displayed on multiple devices in group settings, then collaboration and information accessibility are improved, but security and risk of unauthorized access worsen
Solution Approach 1:
The system performs preliminary actions by establishing session awareness before information is displayed, and proactively monitoring session status. The whiteboard device continuously checks whether the computing device is still active and maintains session validity, deleting information before unauthorized access can occur if the session ends unexpectedly.
Solution Approach 2:
The system implements feedback mechanisms through session awareness monitoring. The whiteboard receives feedback from the computing device about session status, and based on this feedback, automatically deletes information when the session ends. This closed-loop feedback ensures information is retained only during active sessions and removed when no longer needed.
2Loss of information
If information is retained in memory during sessions, then information availability for collaboration is improved, but vulnerability to unauthorized access after session ends worsens
Solution Approach 1:
The system applies dynamics by making information retention dynamic rather than static. Information is retained in memory only during active sessions and is automatically deleted when sessions end. The whiteboard adapts its information storage behavior based on real-time session status, retaining information when needed and removing it when the collaborative context is no longer valid.
3Object-affected harmful factors
If clean desk policies are implemented, then security is improved, but information sharing and collaboration efficiency worsen
Solution Approach 1:
The system implements self-service by automatically managing information security without requiring manual intervention. The whiteboard autonomously monitors session status, determines when sessions end, and deletes information accordingly. This eliminates the need for users to manually clear screens or remember to secure information, providing both security and collaboration efficiency.
Data Source
AI summary
A method, system or computer usable program product for securing displayed information including establishing a session between a first data processing device including a first memory and a second data processing device including a second memory and a display, maintaining session awareness indicating that both the first and second devices are alive in the session, inputting information into the second data processing device during the session producing input information stored in the second memory, and responsive to a determination the session has ended between the first and second device, deleting the input information in the second memory.
